Manual Actions and Automatic Repair Options

The ADVISE FAILURE command can present both manual and automatic repair options. Data Recovery Advisor categorizes manual actions as either mandatory or optional.

In some cases, the only possible actions are manual. Suppose that no backups exist for a lost control file. In this case, the manual action is to execute the CREATE CONTROLFILE statement. Data Recovery Advisor presents this manual action as mandatory because no automatic repair is available. In contrast, suppose that RMAN backups exist for a missing data file. In this case, the REPAIR FAILURE command can perform the repair automatically by restoring and recovering the data file. An optional manual action would be to restore the data file if it wasunintentionally renamed or moved. Data Recovery Advisor suggests optional manual actions if they might prevent a more extreme form of repair such as data file restore and recovery.

In contrast to manual actions, automated repairs can be performed by Data Recovery Advisor. The ADVISE FAILURE command presents an option ID for each automated repair option and summarizes the action.

Data Recovery Advisor performs feasibility checks before recommending an automated repair. For example, Data Recovery Advisor checks that all backups and archived redo logs needed for media recovery are present and consistent. Data Recovery Advisor may need specific backups and archived redo logs.If the files needed for recovery are not available, then recovery is not possible.
